Answer 2

I had a feeling it was switching the sign. My lesson didn't explain it, So Thank you.

Answer 3

your welcome :)

Answer 4

Would it be the same for binomials? If I had to find the conjugate of a binomial would I change all three signs, just the multiplication, or the ones in the parentheses?

Answer 5

give an example?

Answer 6

yu,,ydum i still like that name:P

Answer 7

yummy*

Answer 8

I came up with; (4+6x)(4-sqrt36x^2)
Would I change the plus and the minus. Or the Multiplication in the middle (FOIL) To where it's like (4+6x)/(4-sqrt36x^2)?

Answer 9

or all three.

Answer 10

wait...lemme say that again

Answer 11

when you have \((4+6x)(4-\sqrt{36}x^2)\)you just FOIL
if you had \(\large{{(4+6x)}\over{(4-\sqrt{36}x^2)}}\)you would do \(\large{{(4+6x)}\over{(4-\sqrt{36}x^2)}}\)\(\times\) \(\large{{(4+\sqrt{36}x^2)}\over{(4+\sqrt{36}x^2)}}\)

Answer 12

I know you FOIL When it's just (4+6x)(4−36√x2)
But it tells me to find the conjugate of the expression I made,
So.. What sign(s) would I change?

Answer 13

maybe you werent supposed to have two binomials...just make it (4+6x) and its conjugate (4-6x)
